FIELD OF THE INVENTION

The present invention relates to certain fluoroalkenyl compounds, including, mono, di, and trifluoroalkenylamines, trifluoroalkenylcarboxylic acids, their derivatives and salts, and formulated compositions thereof. It also related to methods of controlling pests that prey on agricultural crops, such as nematodes, insects, and acarids. A novel method of preparing a trifluoroalkenylamine and novel intermediates for this method are also provided.

BACKGROUND OF THE INVENTION

Fluorinated alkenes have long been known to control nematodes and insects when applied to the soil. U.S. Pat. Nos. 3,510,503, 3,654,333, and 3,780,050 all disclose such compounds. More recently, U.S. Pat. No. 4,952,580 disclosed polyhaloalkenes useful as nematocides, some of which were said to have some downward systemic activity, that is, would control to some extent nematode infestation of the root system after application to the plant foliage. The majority of the compounds disclosed by these patents are nonpolar, which is a desirable characteristic for soil-applied pesticides, providing longer effective periods, but is much less effective for foliar application to achieve systemic effects. U.S. Pat. No. 4,950,666 discloses some polar difluoroalkenylalkane compounds useful as systemic insecticides and nematocides. However, there remains a need in the art for nematode, insect, and acarid control agents having improved systemic mobility, and desirably with low effective levels of use.

DETAILED DESCRIPTION OF THE INVENTION

The novel compounds of the present invention are useful for controlling nematode, insect, and acarid infestation of a plant. Many of these compounds, being polar, are highly effective for systemic control, that is, when applied to the foliage or stems of a plant they are able to move through the phloem and xylem of the plant and provide control of nematodes, insects, or acarids at other locations on the plant. It is believed that this control mechanism is a repelling or antifeedant action, rather than a harming action. Others, particularly the nonpolar compounds are effective only when applied directly to the soil. Some compounds can provide both types of control.

The present methods for systemic control of nematodes, insects, and acarids use the phloem mobile compounds of the present invention or those compounds having a mono-, di-, or trifluoroalkene group bearing a CH₂ NHR substituent or a trifluoroalkene group bearing a (C═O)--R substituent, having sufficient polarity to allow for phloem-mobility without eliminating the nematode-controlling activity of the fluoroalkene moiety. There are several different theories concerning phloem mobility, such as what polarity characteristics compounds must have to be sufficiently phloem mobile in order to be relocated downward in a plant. It has been proposed that the polarity of the molecule as a whole must be sufficient for the molecule to be retained in the phloem, but not be so polar as to not enter at all.

To effectively control nematodes or other pests systemically by application to the above-ground surfaces of a plant, compounds must be capable of passing through the cuticle of the foliage or stem of a plant, passing into the phloem, and remaining there long enough to be transported throughout the plant so as to move to untreated areas including the roots. There they may leak out or in some way contact the pests to such an extent that they are killed or repelled and the damage they would do to the plant is reduced or eliminated. During these steps of transport from the treated areas of leaves or stems throughout the plant, a compound may undergo chemical reactions, such as hydrolysis, or biological reactions, such as enzymatic actions. In addition, compounds may be devised which, when placed on the plant, prior to absorption into the plant, may undergo reactions that result in a compound that is readily absorbable, translocatable, and effective in preventing pest damage. An example of such compounds are those having UV-labile protecting groups which when exposed to natural light undergo reaction and result in active and mobile compounds. Another example is silylated amine derivatives.

Therefore, what is placed on the foliage or stem of the plant may not be the compound that is actually transported or the compound that actually controls the pests. Thus, the methods of the present invention provide for compounds that may be transformed through chemical or biological reactions to have proper polarity for systemic activity.

The methods of the present invention include applying 3,4,4-trifluoro-3-butene-1-amine or its salts to the plant locus, preferably to the foliage. Also included are compositions comprising an aqueous solution of 3,4,4-trifluoro-3-butene-1-amine or its salts in an agronomically acceptable carrier.

In the methods described above, in order to control nematodes it is preferred that n is 1 and X, Y, and Z are all F, and more preferably Q₁ is then CH₂ NH₃ ⁺ W⁻, that is, a salt of 3,4,4-trifluoro-3-butene-1-amine. When Q₁ is CH₂ NHR₆, R₆ is preferably an alpha-amino acid linked by a peptide (amide) bond, more preferably a protein amino acid. When Q₁ is (C═O)--R₁₁, R₁₁ is preferably hydroxyl and the compound is thus 3,4,4-trifluoro-3-butenoic acid or a salt thereof, including a salt formed with 3,4,4-trifluoro-3-butene-1-amine, that is, 3,4,4-trifluoro-3-butene-1-amine 3,4,4-trifluoro-3-butenoate.

W⁻ may be any agronomically acceptable anion. This includes, but is not limited to chloride, iodide, bromide, oxalate, sulfate, phosphate, citrate, acetate, or a fluoroalkene carboxylate, for example, F₂ C═CFCH₂ COO⁻.

In addition to the compounds specifically described above, all agronomically acceptable salts of the compounds are within the scope of the present invention. For example, a compound of the present invention having a free amine group may also exist as the protonated form having various anions associated therewith, for example, but not limited to, chloride, bromide, iodide, phosphate, oxalate, sulfate, citrate, and acetate. In addition, a fluoroalkene carboxylate ion, such as F₂ C═CFCH₂ COO⁻, may be the counter-ion. A compound of the present invention having a carboxylic acid or hydroxyl group may exist as the salt having various cations associated therewith, for example, but not limited to, alkali earth metals, such as sodium, calcium, and potassium; magnesium; or quaternary ammonium ions, such as ammonium, mono-, di-, or trialkylammonium, for example, isopropylammonium, or pyridinium. In addition, a fluoroalkenyl ammonium ion, such as F₂ C═CFCH₂ CH₂ NH₃ ⁺, may be the cation. All such compounds and others having similar characteristics, being agronomically acceptable, are encompassed by the present invention.

As used herein, the term "halo", "halide", or "halogen" means fluorine, chlorine, iodine, or bromine or cognates thereof.

The term "alkyl" means straight-chain or branched groups of from one to about seven carbon atoms. The term "lower alkyl" means a such a group containing from one to about four carbon atoms. The term "aliphatic" means saturated or unsaturated, branched or straight-chain, alkyl groups having from one to ten carbon atoms.

The term "alkoxy" means a lower alkyl group bonded via an oxygen atom. The term "alkylthio" means a lower alkyl group bonded via a sulfur atom. The term "alkoxycarbonyl" means the lower alkyl ester of a carboxyl group.

The term "aliphatic amine" means an aliphatic group wherein at least one hydrogen is replaced with --NH₂. The term "aliphatic carboxylic acid, its esters, thiol esters, and amides" means an aliphatic group wherein at least one carbon is a carboxylic group, --COOH, or is the lower alkyl ester, lower alkyl thiol ester, or amide thereof.

The term "aromatic group" or "aryl" means phenyl, optionally substituted with at least one group selected from hydroxy, alkoxy, halo, nitro, amino, thiol, alkylthio, carboxyl, alkoxycarbonyl, and phenyl. It should be obvious to one of ordinary skill in the art that heterocycles could also be used for the aromatic group, for example, thiadiazole, pyridine, thiazole, isothiazole, oxazole, pyrazole, triazole, benzothiazole, thiophene, furan, and the like, all of which may also be optionally substituted.

As used herein, the phrase "amino acid amide of Q" (or Q₁) means that R₆ is an amino acid coupled via a peptide (amide) bond to the N of CH₂ NHR₆. This amino acid may be a natural, i.e., protein, amino acid or a nonnaturally occurring amino acid. The amino group of the amino acid may be a substituent of any carbon in the group, for example, alpha, beta, or gamma to the carbonyl.

The term "alkyl or aryl hydrazine" means a hydrazine group substituted with a lower alkyl or phenyl group, which in turn may be optionally substituted. The term "alkyl or aryl sulfonamide" means a sulfonamide group substituted with a lower alkyl or phenyl group, which in turn may be optionally substituted.

COMPOUND SYNTHESIS

The compounds of the formula above wherein X, Y, and Z are F and Q is a --CH₂ N-- derivative are generally prepared by first obtaining the desired trifluoroalkenylamine, which when n equals 1 is 3,4,4-trifluoro-3-butene-1-amine. One method of preparing this compound is disclosed in Example 6 of U.S. Pat. No. 4,952,580, the full text of which is incorporated herein by reference. The present invention provides an improved and novel method of making this compound. Surprisingly, 4-bromo-1,1,2-trifluoro-1-butene, which is commercially available, may be directly converted by first reacting it with a tosylate salt, for example, silver tosylate, a mesylate salt, or other sulfonic acid leaving group. The resulting intermediate, for example, 3,4,4-trifluoro-3-butene-1-tosylate or 3,4,4-trifluoro-3-butene-1-mesylate, is a novel compound. This step is followed by conversion to the phthalimide derivative using a phthalimide salt, such as potassium. Advantageously, this may be accomplished without first isolating the tosylate or mesylate intermediate. The phthalimide is then converted to the desired amine by reaction with hydrazine. This novel process for preparing 3,4,4-trifluoro-3-butene-1-amine has the advantage of having an improved yield compared to the prior reported synthesis method, which is at least partially attributable to avoiding the elimination of hydrogen bromide during the conversion of the bromo compound. N-(3,4,4-trifluoro-3-butenyl)phthalimide is thus produced in greater than 80 percent yield and converted to the desired amine in greater than 85 percent yield. Also, advantageously, when silver tosylate is the reactant chosen to provide the leaving group, the silver ions may be recovered and silver tosylate regenerated.

Longer chain alkenyl amines may be made through several routes. For example, to produce a compound of the present invention wherein n equals 3, ethylene oxide can be reacted with 4-bromo-1,1,2-trifluoro-1-butene by known methods to produce 6-hydroxy-1,1,2-trifluoro-1-hexene. This compound may then be converted to the amine salt using tosyl chloride and phthalimide as described above for the butene. Alternatively, 1,1,2-trichloro-1,2,2-trifluoroethane (F113) may be reacted with a terminal alkene or alkyne bromo compound under redox conditions, as described in Tetrahedron Letters, 31, pp 1307-1308, 1990. The reaction product is subsequently dechlorinated with Zn to produce a trifluoroalkene bromide, which can be converted to the desired amine as described above for the butene. A third method is exemplified in Synthesis Example 40, below.

Difluoro alkenyl amines may be made by two different methods, depending on the position of the fluorines. To produce a terminal difluoro compound, such as 4,4,difluoro-3-butene-1-amine hydrochloride, the following route may be used: ##STR3## The other difluoro compounds, that is, wherein one of X and Y is H and Z is F, are made by the following route: ##STR4## wherein m is 2, 4, 6, 8, 10, or 12. LAH is lithium aluminum hydride. The E and Z forms may be isolated by distillation from the mixture of products obtained from this reduction.

Likewise, monofluoro compounds of the present invention are made by two different routes depending on whether the fluorine is terminal or internal, as illustrated in the following schematics: ##STR5## To produce an internal monofluoro compound, the following scheme may be used: ##STR6##

Many of the other compounds of the present invention where Q is CH₂ NHR₆ are then easily prepared by reacting a selected reactant with the appropriate fluoroalkenyl amine or a salt thereof by methods generally known to those skilled in the art. For example, to prepare amide derivatives, wherein R₆ is a --(C═O)-derivative, the appropriate acid is reacted with the selected fluorinated alkenylamine by conventional techniques. The acid may be in the form of the acid halide or anhydride for the most efficient reaction with the amine. For example, when R₆ is (C═O)--CF₃, trifluoroacetic anhydride is used. When the succinamic acid derivative is desired, succinic anhydride may be used, and when the oxalic acid derivative is desired, the acid chloride may be used.

Where R₆ is an alpha-amino acid linked by a peptide (amide) bond to the nitrogen of CH₂ NHR, that is, when R₆ taken with the nitrogen is an alpha-amino acid amide, typical peptide or amide coupling reagents, such as carbonyldiimidazole or DCC, may be used to effect the peptide (amide) bond. For substituted acid groups, any functional group which could affect or be affected by the peptide (amide) bonding must be properly protected. For example, an amine functionality would be protected by a t-BOC group. Acids or alcohols can be protected as benzyl or t-butyl esters or ethers, respectively. Thiols can be protected by a trityl group. Deprotection, to produce the desired compound, would follow, using known methods.

Where R₆ is an aliphatic carboxylic acid, there are two synthetic routes. The desired fluoroalkenylamine may be reacted with the appropriate electrophilic reagent, for example, a haloalkylcarboxylate ester. The resulting ester may be used or hydrolyzed to the free acid, which may then be derivatized by known methods to its salts, amides, and thiol esters. Alternatively, the bromofluoroalkene may be reacted with the appropriate amino acid.

Where R₆ is a lower aliphatic group, the selected fluoroalkenylamine is reacted with the appropriate electrophilic agent, for example, an alkyl halide, such as methyl iodide. The amine is preferably present in excess to the alkyl halide in order to minimize further amine substitution.

Where R₆ is a C₁ -C₁₂ alkyl amine, the bromide or tosylate, instead of the amine, is generally used as the starting material and reacted with excess of the desired alkyldiamine, having one amine group protected. Thereafter, deprotection by known methods will result in the desired product.

Where R₆, taken with the nitrogen of the Q or Q₁ group CH₂ NHR₆, is guanidine, the selected fluoroalkenylamine, in the form of a salt as described above, is reacted with cyanamide.

Where R₆ taken with the nitrogen of the Q or Q₁ group CH₂ NHR₆ is an alkyl or aryl sulfonamide, optionally substituted, the selected fluoroalkenylamine is reacted with the appropriate sulfonyl chloride, for example, tosyl chloride.

Where R₆ taken with the nitrogen of the Q or Q₁ group CH₂ NHR₆ is a urea, carbamate, thiocarbamate, semicarbizide, or hydrazine, the selected fluoroalkenylamine is first converted to the isocyanate, i.e., where Q is CH₂ N═C═O. This isocyanate is prepared by reacting the amine with diphenylcarbamoyl chloride, followed by high temperatures to produce the isocyanate as in the following schematic. ##STR7##

From the isocyanate the other compounds may be made by reaction with ammonia or amines to produce ureas; alcohols to produce carbamates; thiols to produce thiocarbamates; or hydrazines to produce semicarbizides. In the last instance, the hydrazine must be protected, for example, with a t-BOC group and subsequently deprotected to produce the semicarbizide.

Compounds wherein Q is CH₂ N═CH--R₂ are also prepared from the appropriate fluoroalkenylamine, for example, 3,4,4-trifluoro-3-butene-1-amine. It is reacted using known methods with the appropriate aromatic aldehyde, preferably a benzaldehyde, for example, p-(N,N-dimethylamino)-benzaldehyde or 2-hydroxy-5-nitrobenzaldehyde.

Compounds wherein Q is CH₂ N⁺ R₃ R₄ R₅ W⁻ may sometimes be prepared from the fluoroalkenylamine, for example, 3,4,4-trifluoro-3-butene-1-amine. The amine group is quaternized by known methods, for example by an excess of alkyl halide, for example methyl iodide. Thus the compound 3,4,4-trifluoro-3-butenyl trimethyl ammonium iodide could be produced.

For other compounds wherein Q is CH₂ N⁺ R₃ R₄ R₅ W⁻, the fluoroalkenyl bromide may be used. For example, when R₃, R₄, and R₅ are taken together with the nitrogen to form a cyclic quaternary ammonium group, the appropriate cyclic amine, for example hexamethylenetetramine, is reacted with the fluoroalkenyl bromide to produce the desired quaternary ammonium compound. When one of R₃, R₄, and R₅ is a hydroxyl group, the compound is prepared by reacting the fluoroalkenyl bromide with excess O-trimethylsilyl-hydroxylamine to produce the O-trimethylsilyl-protected fluoroalkenylhydroxylamine, which is then hydrolyzed with methanol, followed by treatment with acid, to produce the desired hydroxyl amine salt.

The compound wherein Q is CH₂ NO₂ may be prepared by known methods from the fluoroalkenyl bromide and silver nitrite.

The compounds of the present invention that are trifluoroalkenecarboxylic acids and derivatives, that is, where Q is (C═O)--R₁₁ (and X, Y, and Z are F) are similar to some of the compounds disclosed in U.S. Pat. No. 4,950,666, but cannot be made by the same Witrig reaction procedure. They are prepared by a completely different route, by converting 4-bromo-1,1,2-trifluoro-1-butene to the alcohol via an ester intermediate. For example, phenyl acetic acid is used to produce the phenyl acetate ester of trifluorobutene, then hydrolyzed to produce trifluorobutenol, and then oxidized to the acid, as in the following schematic: ##STR8## Longer chain acids, where n is 3, 5, etc., may be made in the same manner from the longer chain halides made as described above. Derivatives of these acids, e.g., salts, ester, amides, etc., may be readily made by methods known to those skilled in the art.

Details of such reactions are given in the following specific Synthesis Examples, which are provided for illustration and are not meant to be limiting in any way.

SYNTHESIS EXAMPLE 1 Preparation of 3,4,4-trifluoro-3-butene-1-amine and its salts.

The reaction mixture, protected from the light, is then heated and stirred overnight at reflux. After cooling, the precipitate is filtered off, and the solvent removed from the filtrate under vacuum. Ethyl acetate, 100 mL, is added to the residue of the filtrate and then washed three times with water and dried over magnesium sulfate. To this ethyl acetate solution of 3,4,4-trifluoro-3-butene tosylate is added 25 mL DMF and 16.7 g (0.09 mole) potassium phthalimide. This reaction mixture is stirred at reflux for 24 hrs.

(b) To 13.91 g (0.054 mole) of the product of step a, dissolved in 100 mL of ethanol, is added 1.76 g (0.054 mole) anhydrous hydrazine. The reaction mixture is then stirred at reflux for 3 hrs. Conc. HCl, 40 mL, is then added slowly through the reflux condenser, and the mixture stirred two more hrs at reflux. After cooling, the reaction mixture is diluted with water; the precipitate is filtered off and washed with additional water, which is combined with the filtrate.

COMPOSITIONS

In normal use, the compounds usually will not be employed free from admixture or dilution, but ordinarily will be used in a suitable formulated composition compatible with the method of application and comprising an effective amount of the compound. The compounds of this invention, like most agricultural agents, may be blended with agriculturally acceptable surface-active agents and carriers normally employed for facilitating the dispersion of active ingredients, recognizing the accepted fact that the formulation and mode of application may affect the activity of the material. The present compounds may be applied, for example, as sprays, dusts, or granules, to the area where pest control is desired, the type of application varying with the pest and the environment. Thus, the compounds of this invention may be formulated as granules of large particle size, as powdery dusts, as wettable powders, as emulsifiable concentrates, as solution, and the like.

Granules may comprise porous or nonporous particles, such as attapulgite clay or sand, for example, which serve as carriers for the present compounds. The granule particles are relatively large, a diameter of about 400-2500 microns typically. The particles are either impregnated with the compound of the invention from solution or coated with the compound, adhesive sometimes being employed. Granules generally contain 0.05-10%, preferably 0.5-5%, active ingredient.

Dusts are admixtures of the compounds, with finely divided solids such as talc, attapulgite clay, kieselguhr, pyrophyllite, chalk, diatomaceous earths, calcium phosphates, calcium and magnesium carbonates, sulfur, flours, and other organic and inorganic solids which act as carriers for the compound. These finely divided solids have an average particle size of less than about 50 microns. A typical dust formulation contains 1 part of compound and 99 parts of talc.

The compounds of the present invention may be made into liquid concentrates by dissolution or emulsification in suitable liquids and into solid concentrates by admixture with talc, clays, and other known solid carriers used in the agricultural chemical art. The concentrates are compositions containing about 5-50% active compound and 95-50% inert material, which includes surface-active dispersing, emulsifying, and wetting agents, but even higher concentrations of active ingredient may be employed experimentally. The concentrates are diluted with water or other liquids for practical application as sprays, or with additional solid carrier for use as dusts.

A typical 50% wettable powder formulation would consist of 50.0% (wt/wt) of active ingredient, 22.0% attapulgite diluent, 22.0% of kaolin diluent, and 6.0% sodium salts of sulfonated Kraft lignin emulsifier.

Typical carriers for solid concentrates (also called wettable powders) include fuller's earth, clays, silicas, and other highly absorbent, readily wetted inorganic diluents. A suitable solid concentrate formulation may contain 1.5 parts each of sodium lignosulfonate and sodium lauryl sulfate as wetting agents, 25 parts of active compound and 72 parts of attapulgite clay.

Manufacturing concentrates are useful for shipping low melting products of this invention. Such concentrates are prepared by melting the low melting solid products together with one percent or more of a solvent to produce a concentrate which does not solidify on cooling to the freezing point of the pure product or below.

Useful liquid concentrates include the emulsifiable concentrates, which are homogeneous liquid or paste compositions readily dispersed in water or other liquid carriers. They may consist entirely of the active compound with a liquid or solid emulsifying agent, or they may also contain a liquid carrier such as xylene, heavy aromatic naphthas, isophorone and other relatively non-volatile organic solvents. For application, these concentrates are dispersed in water or other liquid carriers and normally applied as sprays to areas to be treated.

A typical 50 gram per liter emulsifiable concentrate formulation would consist of 5.9% (wt/wt) of a compound of the invention; as emulsifiers; 1.80% of a blend of the calcium salt of dodecylbenzene sulfonate and nonionic 6-molar ethylene oxide condensation product of nonylphenol, 2.70% of a blend of the calcium salt of dodecylbenzene sulfonate and a nonionic 30-molar ethylene oxide condensation product of nonylphenol, 1.50% of a nonionic paste of polyalkylene glycol ether, and 88.10% refined xylene solvent.

Typical surface-active wetting, dispersing, and emulsifying agents used in agricultural formulations include, for example, the alkyl and alkylaryl sulfonates and sulfates and their sodium salts; alkylamide sulfonates, including fatty methyl taurides; alkylaryl polyether alcohols, sulfated higher alcohols, polyvinyl alcohols; polyethylene oxides; sulfonated animal and vegetable oils; sulfonated petroleum oils; fatty acid esters of polyhydric alcohols and the ethylene oxide addition products of such esters; and the addition products of long-chain mercaptans and ethylene oxide. The surface active agent normally comprises about 1-15% by weight of the active ingredient.

Other useful formulations include simple solutions of the active ingredient in a solvent in which it is completely soluble at the desired concentration, such as water, acetone, or other organic solvents. The preferred formulation for foliar application is an aqueous solution, more preferably containing glycerin and a surfactant, such as Tween®20, and most preferably 1% glycerin and 0.1% Tween®20.

The compositions may be formulated and applied with suitable pesticidal active ingredients, including insecticides, acaricides, fungicides, plant regulators, herbicides, fertilizers, etc.

METHODS OF USE

The present invention provides methods of controlling various pests that prey on agricultural crops, namely nematodes, insects, and acarids. An infestation of a plant by any of these pests may be controlled by applying to the plant locus an effective amount of any of the compounds of the present invention. The application may be made in a variety of ways, including applying the compound or a composition containing it to the soil before or after planting or emergence, to the seed or seed pieces prior to or at planting, and to the plant foliage, stems, for trunks. The treatment may be made more than once during a growing season with one or more days between treatments. An appropriate treatment schedule will depend on the life cycle of the pest to be controlled, ambient temperatures, and moisture levels. In addition the age or size of the plant may influence the treatment schedule.

The methods of the present invention may be carried out on a variety of crops. These include, but are not limited to, fruit and vegetable crops, such as potatoes, sweet potatoes, carrots, tomatoes, grapes, peaches, citrus, bananas, corn, and soybeans; tobacco; and cotton.

Compounds of the present invention may be used to control any of the phytopathogenic nematodes. Insects which may be controlled by the methods of the present invention include, but are not limited to, foliar pests such as green peach aphids, and soil-borne pests such as southern corn rootworm. Acarids which may be controlled by the methods of the present invention include, but are not limited to two spotted spider mites. Tests conducted with a few of the compounds of the present invention revealed no significant level of control of tobacco budworm or Colorado potato beetle.

TEST EXAMPLES

A. Tomato and soybean nematode tests

Compounds of the present invention, prepared as described above, were tested for effectiveness in controlling root knot nematode (Meloidogyne incognita). The compounds were tested by foliar application and by soil-drench application. The results of four different methods of testing are shown in the Table A. The methods were as follows:

Method 1.

Foliar application to tomato plants

Tomato plants, cv `Rutgers`, were grown one plant per pot in 2.5×18.8 cm pots. Nineteen days after planting, both sides of the leaves were sprayed with the test compound at the concentrations indicated in Table A. The test compounds were prepared by first dissolving each in water or acetone, as appropriate, and mixing with water containing 0.05% Tween® 20 and 1.0% glycerin. For each treatment rate, four plants were sprayed with 29 mL of solution. The plants were allowed to dry before transferring to growth chambers maintained at 25°-28° C. There they were sub-irrigated to prevent the leaves from dripping onto the soil. Two to three days after chemical applications, a suspension of J2 larvae, 4500 per pot, was pipetted onto the roots and soil. Three weeks after inoculation, the amount of galling on washed roots was compared to the water-treated controls. The results are reported as percent disease control.

Method 2.

Foliar application to tomato plants

The Method 1 steps were followed except that (1) the tomato plants were grown in 7.5×6.3 cm² pots and (2) inoculation was made by pipetting approximately 8000 eggs in 5 mL onto the soil of each pot at 20 days after planting. The next day each plant was sprayed with 4 mL of treatment solution. The extent of galling was determined at three weeks after inoculation. A rating scale of 0 to 3 was used, 0 being extensive galling and 3 being no galling.

Method 3.

Soil application to soybean seeds

Two soybean seeds, cv `Williams,` were placed in each 2.5 cm² pot and inoculated with approximately 8000 eggs. Test compounds were added at 1 mg per pot, in 2 mL of solution prepared as described in Method 1. One pot per treatment level was used. The seeds were covered with vermiculite and lightly watered. The plants were subirrigated once a day for four weeks. The washed roots of the plants were then evaluated as in Method 2.

Method 4.

Soil application to tomato plants

The Method 2 steps were followed except that the day after inoculation, treatments were applied to the soil by pipetting 4 mL of treatment solution onto the soil in each pot. Galling was evaluated 3 weeks after inoculation as in Method 2.

Method 5.

Soil and Foliar application to tomato plants

Steps from both Methods 2 and 4 were followed except that tomato plants were grown in 5.0×5.0 cm² pots and inoculation was made by pipetting approximately 7000 eggs in 4 mL onto the soil of each pot 20 days after planting.

B. Soybean cyst nematode test

Compound 1 was tested for effectiveness in controlling the soybean cyst nematode (Heterodera glycines) by foliar application. A sandy soil was infested with approximately 100 soybean cyst nematode eggs per cc of soil. Approximately 350 cc of the infested soil was placed into each 4-inch square pot. Three soybean seeds, Glycine max variety Williams-82, were placed on top of the infested soil and covered with a layer of uninfected sandy soil.

Foliar applications were begun when the plant reached the unifoliate leaf stage. Applications were made as a single unifoliate spray or in sequential sprays at unifoliate plus seven days or unifoliate plus seven and plus fourteen days. The test compound was dissolved in water with 1% glycerin and 0.1% Tween®20. At each spraying, the soil surface was covered to prevent soil contact. The applications, using the rates listed below, were made to the point of runoff.

Final disease evaluations were made approximately five weeks after planting by counting the number of cysts on each root system. Control was determined by percent reduction in average number of cysts per root on treated plants as compared to the inoculated, water/glycerin/Tween®20 formulation control.

C. Insect and acarid tests

Compounds of the present invention were tested for effectiveness in controlling the two spotted spider mite, Tetranychus urticae or TSSM; the green peach aphid, Myzus persicae or GPA; and the southern corn rootworm, Diabrotica undecimpunctata or CRW, by foliar application.

In initial tests to determine activity against aphids, three week old chinese cabbage (Brassica chinensis) were infested with green peach aphid adults from leaf pieces of culture plants. Newly infested plants were left in growth chambers until insect populations increased to greater than forty insects per leaf. The most uniformly infested plants were selected for testing purposes. Appropriate amounts of test materials were dissolved directly in a water formulation with 1% glycerin and 0.1% Tween®20. Plants were sprayed to runoff on both upper and lower leaf surfaces. Five plants for each test solution were sprayed. The sprayed plants were transferred to a hood where they were kept until the spray had dried. Plants were transferred back to growth chamber for five days before making final percent control ratings.

For two spotted spider mite tests, soybeans (Glycine max) grown to the unifoliate stage, or cotton (Gossypium hirsutum) grown to the full cotyledon stage were utilized. Leaf discs made using a #6 cork borer were removed from culture plants infested with adult mites and eggs and placed on the upper unifoliate leaf surface of the soybean plants or cotyledons of the cotton plants. After the mites had migrated and infested the entire plant (6-10 days), the leaf discs were removed. The most uniformly infested plants were selected for testing purposes and sprayed with test solutions as described above using five plants per treatment. Five days after application all leaves were examined and adult mites on the underside of leaves were counted. Control was calculated by percent reduction in average number of mites on treatment plants as compared to the inoculated water/formulation control.

Tests against southern corn rootworm were conducted using four corn (Zea mays) seeds planted in each of three inch pots and grown in the greenhouse until approximately six inches tall. Small holes were scratched into the soil surface near the roots of each plant and ten first instar larvae of southern corn rootworm were placed in the holes. One day after infestation, leaves of the corn plants were sprayed to runoff with test solutions of the same formulation as above. Seven days after spraying, larvae were recovered from soil by soaking pots in 10M MgSO4 solution. The number of living larvae were averaged for each treatment and the percent control calculated.

D. Potato seed treatments

Compound 1 of the present invention was tested for effectiveness in controlling root knot nematode (Meloidogyne incognita) by application to potato seed pieces. The compound was also tested by foliar application as a comparison.

Potato tubers were cut so as to retain at least two eyes per piece. For each treatment level the tuber pieces were weighed and placed in a mixture of the compound and enough powdered clay to expose the pieces to the specified treatment rate at a constant treatment volume. The pieces were agitated until the surfaces were coated and planted, one piece per one-gallon pot. Each pot was inoculated with 50,000 eggs.

In the foliar application, the plants were each sprayed with a solution of Compound 1 in water with 1% glycerin and 0.05% Tween® 20. The spray was applied so as to evenly distribute the compound over the surfaces of all leaves. Each plant was sprayed four times, two weeks apart, and was inoculated as for the tuber pieces either at planting or at three days prior to each treatment. The results are shown in Table D.
